Equalizer pedal

I am looking for a equalizer pedal, that is able to cut off especially middle and high frequencies, to get just really the low sound. my problem is that my bass is active, and i don´t want to turn the active off or doesn´t have time for this during the songs.
i currently got the boss ge-7, which is good for me for cutting the middle frequenzies or boost the lows. but i need more option to get the mids and highs nearly completely out of my sound.

I started that thread, and the answer was literally right in front of me in a pedal I already had..Aguilar Octamizer. Just turn the octave level off and you're left with the clean signal cut off as low as you want with the 'clean tone' knob.

i watched some chris hargreaves dubstep vids, and i think he uses the Bass MuRF(MF-105B). The pedal isn´t in production anymore. So does anyone know if there is a similar pedal out there, which can produce the subs as well as this pedal?

For what you want, you can cut the mids & highs AND boost the lows AND set the input/output levels so when you hit the ON switch, the EQ and decibel level is what you want....instantly. I've used it as a solo boost this way(except with a nearly flat EQ).
